In January 2018 we announced that Piwik is now Matomo 🎉

As part of the renaming efforts we're updating all our websites, tools, core app, plugins, ie. everything!

Renaming checklist left to do:

• make the build files matomo.zip and matomo.tar.gz, as well as the directory inside the builds should be called matomo
• plugin CustomPiwikJs to be renamed eg. CustomJsTracker --> see Rename CustomPiwikJs plugin to CustomMatomoJs (or CustomTrackerJs) #13604
• plugin AnonymousPiwikUsageMeasurement to be renamed (out of scope for Matomo 4)
• HTTP Tracking API endpoints: piwik.js and piwik.php
• JavaScript tracking sdk with objects like Piwik and window.Piwik and methods like getPiwikUrl
• Plugin developers, core platform uses namespace Piwik + some objects called "Piwik"
• Rename events eg Piwik.getJavascriptCode
• cookie names eg piwik_auth
• URL parameter like piwik_campaign to also support matomo_campaign --> done with Allow using matomo prefixed parameters for campaigns such as matomo_campaig/mtm_campaign #15957
• HTTP API methods eg. ExampleAPI.getPiwikVersion -> 3.3.0
• DB prefix like piwik_ -> 3.3.0
• Remove --piwik-domain console parameter (see Renames console to Matomo #13192) - Will be done with Removes deprecated console param --piwik-domain #15503
• After a successful auto-update, the screen shows Piwik is now Matomo and a big image. Be good to remove both. --> Will be done with Removes Piwik is now Matomo from update screen #15504
• Marketplace URL parameters like "piwik_version"
• plugin.json parameters like require "piwik"
• CSS classes etc (out of scope for Matomo 4)
• angular directives like piwik-foobar (out of scope for Matomo 4)
• Remove Piwik font (already "renamed" to Matomo in Renames piwik font to matomo #12489)
• Tracker proxy: Add matomo.php with keeping BC + Update [faq])https://matomo.org/faq/how-to/faq_132/) Update file names to matomo.* + FAQ tracker-proxy#55
• update all doc blocks with new name / url --> Update codebase doc blocks with new name Matomo #15857
• ... and more

In the case of Matomo core platform we want to keep things backward compatible for users including HTTP APIs users or users of the JavaScript SDKs.

Assigning to Matomo 4.0.0 but hopefully we can tackle a few of the list, and make progress on the others, during Matomo 3.x 🚀
